New Guinea impatiens plant named ‘SAKIMP032’

ABSTRACT

An  impatiens  plant particularly distinguished by having a many beautiful red flowers with a red-purple eye, a strong root system, and spreading habit, is disclosed.

Genus and species: Impatiens hybrida hort.

Variety denomination: ‘SAKIMP032’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of New Guinea impatiens plant, botanically known as Impatiens hybrida hort., and referred to by the variety name ‘SAKIMP032’ and characterized by having many flowers, a strong root system, and a spreading habit. Impatiens variety ‘SAKIMP032’ originated from a hybridization in Misato, Japan in September of 2009. The female parent was a proprietary impatiens breeding line named ‘NF-572A2’ (unpatented) having orange colored flowers. The male parent was a proprietary impatiens breeding line named ‘NE-252B’ (unpatented) having scarlet colored flowers.

‘SAKIMP032’ was selected in September 2009 from the F₁ progeny. From May through August of 2011, ‘SAKIMP032’ was evaluated for its performance. In May through August of 2012, ‘SAKIMP032’ was first vegetatively propagated, cultivated, and transplanted to the greenhouse and to the field for outdoor evaluation. ‘SAKIMP032’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Salinas, Calif.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Salinas, Calif.

-   -   1. Red flowers with a red-purple eye;     -   2. A strong root system; and     -   3. A spreading habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKIMP032’. Data was collected on plants grown four months from transplant into 6-inch posts from rooted cuttings in Salinas, Calif., under greenhouse conditions in the spring 2014. Plants were pinched once during growth. Color references are to The Royal Horticultural Society of London colour chart (R.H.S.), 4^(th) edition (2001).

The             vegetative cuttings were propagated for five to six weeks.             The base of the cuttings were dipped for 1 to 2 seconds in a             1:9 solution of DIP 'N GROW (1 solution: 9 water) root             inducing solution immediately prior to sticking into the             cell trays. Cuttings were stuck into plastic cell trays             having 98 cells, and containing a moistened peat moss-based             growing medium. The cuttings were misted with water from             overhead for 10 seconds every 30 minutes until sufficient             roots were formed. Rooted cuttings were transplanted and             grown in 20 cm diameter plastic pots in a glass greenhouse             located in Salinas, Calif. Pots contained a peat moss-based             growing medium. Soluble fertilizer containing 20% nitrogen,             10% phosphorus and 20% potassium was applied once a day or             every other day by overhead irrigation. Pots were             top-dressed with a dry, slow release fertilizer containing             20% nitrogen, 10% phosphorus and 18% potassium. The typical             average air temperature was 24° C. -   Plant description:     -   -   Habit and form.—Spreading.         -   Height.—38.0 cm from soil line to the top of the plant; 1.0             cm from soil line to first node; and 2.0 cm from the first             node to the second node.         -   Spread.—68.0 cm.         -   Number of branches.—4 main, 8 total.         -   Length of branches.—16.0 cm.         -   Diameter of branches.—1.2 cm.         -   Life cycle.—Annual; a tender perennial in warm climates.         -   Time to bloom from propagation.—6 to 8 weeks.         -   Flowering requirements (season).—Spring to first frost.         -   Temperature tolerances.—Heat tolerant. -   Stems:     -   -   Stem color.—RHS 59A (Red-Purple).         -   Anthocyanin color.—Absent.         -   Stem pubescence.—Absent.         -   Stem description.—Smooth; circular cross-section.         -   Stem length.—26.0 cm.         -   Stem diameter.—0.5 cm.         -   Internode length.—8.0 cm. -   Branches:     -   -   Branch color.—RHS 59A (Red-Purple).         -   Anthocyanin color.—Absent.         -   Branch pubescence.—Absent.         -   Branch description.—Smooth; circular cross-section.         -   Branch length.—16.0 cm.         -   Branch diameter.—1.2 cm.         -   Internode length.—6.0 cm. -   Leaves:     -   -   Leaf arrangement.—Whorled with up to 5 leaves per node.         -   Leaf shape.—Lanceolate; curled opposite if only 2 leaves at             one node.         -   Leaf apex.—Accuminate.         -   Leaf base.—Attenuate.         -   Leaf margin.—Ciliate.         -   Leaf surface.—Dull, waxy.         -   Leaf length.—9.0 cm.         -   Leaf width.—3.5 cm.         -   Leaf color.—Upper: RHS 147A (Yellow-Green).

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘SAKIMP032’ is most similar to the commercial New Guinea impatiens variety ‘SAKIMP030’ (U.S. Plant Pat. No. 25,015); however, there are differences as listed in the table below:
